Abstract

The invention discloses an environmental test chamber for monitoring purification effect of air purifying products, which comprises a sealed box body, a sample introducing / sampling system, a temperature / humidity control system, a light source control system, an air channel internal circulation and air flow rate control system, an air exchange system and a control panel; in the environmental test chamber of the invention. an environment compounding cavity, independent of the external environment, is formed by the sealed box body, and environmental parameters in the environmental test chamber can be regulated and controlled by the sample introducing / sampling system, the temperature / humidity control system, the light source control system, the air channel internal circulation and air flow rate control system and the air exchange system so as to simulate different environmental conditions. The environmental test chamber of the invention has the advantages of providing a test environment with good stability and uniformity and comprehensively simulating the actual working environment of air purification, so that the environmental test chamber can be used for monitoring the purification effect of air purifying products and is also applicable for monitoring the purification effect of nanometer purifying products based on photocatalysis.

Description

technical field

[0001] The invention relates to an environmental test chamber, in particular to an environmental test chamber for monitoring the purification effect of air purification products. Background technique

[0002] With the improvement of living room decoration grades and the widespread use of paint, high-grade stone and furniture, etc., there are a wide variety of indoor chemical pollutants, which cause a series of problems for the human body. The environmental monitoring report shows that indoor air chemical pollutants mainly include: formaldehyde, radon, ammonia, benzene series and volatile organic compounds (TVOC), etc. If you stay in an environment with high concentration of formaldehyde for a long time, the chances of suffering from lung cancer and liver cancer will be greatly increased ; Benzene can damage the human blood circulation system and cause leukemia. It can be seen that indoor air quality will directly affect people's physical health, mental healt...
